| Well will not add all things together. It has been said that several times in history that a volcanoes' activities has affected climates at least on a local area. In the views of some scientist they claim that the smoke from active volcanoes hid the sun from the earth and that this was a precursor to the ice age. This cannot be proved in my thoughts but the ash from the eruption of Saint Helen's in the USA darkened the sky for many miles and know that you can find something on this. Also check out the Krakatoa volcano that was in Hawaii area. Also Tsunamis are said to be caused from under ground eruptions of volcanoes in the oceans. |
